. t HASP-HOOK.

SPECIFICATION forming part of Letters Patent No. 290,119, dated December 11, 1883.

' I Application filed June 30, 1883. (No model.)

To rtZZ whom it may concern.-

pressing his thumb against this projection 0,

Be it known that I, GEORGE H. SARGENT, of the tongue will be readily turned into the New York, in the county of New York and State of New York, have invented a new Improvement in Hasp-Hooks; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full,

i clear, and exact description of the same, and

which said drawings constitute part of this specification, and represent, in

Figure l, a perspective view; Fig. 2, a sectional side view; Fig. 3, a transverse section through the back of the hook, showing the tongue turned up against the back.

This invention relates to an improvement in hasp-hooks, the'object being to automatically lock the hook when engaged with its staple or keeper; and it consists in a tongue hinged to the body of the hook oppositethe point, and extending across the mouth, combined with a spring, the action of which is to force and hold the tongue across the mouth, but yield to permit the point of the hook to enter the staple, the said hook constructed with an extension or projection, whereby it may be readily turned away from the mouth for the disengagement of the hook, as more fully hereinafter described.

A represents the body of the hook, one end, constructed with an eye, B, or otherwise, for a hinge-like attachment, the other end terminating in a hook, 0.

At the hook end of the body atonguepiece,

D, is hinged, as'at a. The hub of the tongue is constructed with a shoulder, b, and in arecess in the body a spring, d,'is arranged to bear against the shoulder b above the pivot; hence the tendency of the spring is to force 40 the tongue into a position across the mouth of the hook. The length of the tongue is such t as to practically close the mouth of the hook,

but so that as the hook is presented to the staple, and the point forced therein the tongue piece will be turned up, as seen in broken lines, Fig. 2, to permit the engagement of the staple, and then the tongue will spring back to close the mouth, to, prevent accidental disengagement of the hook from the staple.

From the hub a projection, e, is formed,

preferably so as to standbeneath the body of the hook, as shown, and so that, the person open position, as seen in broken lines, for the disengagement of the hook.

To prevent the tongue from obstructing the free passage of the hook onto the staple, I recess the tongue upon its upper sidethat is, make it substantially. concavo-convex in trans- 6c verse sectionthe concave side of the tongue corresponding to the shape of the part of the hook against which it turns, as seen in broken lines, Fig. 2, and in Fig. 3, so that the tongue in its open position closes, as it were, upon that side of the hook, and thus leaves the hook open and free to engage the staple without interfering therewith, as well as to readily" disengage.

I claim- 1. The herein-described hasp-hook, consisting of the body A, constructed at one end for attachment, and at the other with a hook, G, the mouth of the hook at substantially right angles to the body. combined with a tongue, 7 D, hinged to the body, and extending across the mouth of the hook, constructed with a shoulder, b, and a spring arranged in a recess in the body in rear of and so as to bear against said shoulder, substantially as described.- so

2. The combination of the body A, constructed at one end for attachment, and the other with a hook, O, the mouth of the hook at substantially right angles to the body, a tongue, D, hinged to the body, extending 8 5 across the mouth of the hook and constructed with a shou1der, b, and with a thumb-piece,

e, and a spring arranged in a recess in the body in rear of and so as to bear against the said shoulder, substantially as described.

3. The combination of the hook A O, the mouth ofthe hook at substantially right angles to the body, the tongue D, hinged to the body and extending across the mouth of the hook, the said tongue recessed upon its upper 5 side corresponding to the shape of the inside of the hook, and a spring in a recess in the body in rear of and so as to hold the tongue across the mouth of the hook, substantially as described.
